How can COLORBOND® Coolmax® steel help me meet the BCA Sec J?
Sec J requires you to verify the energy efficiency of the building from a heating and cooling perspective. This is typically done in one of two ways: • Comply with a series of Deemed to Satisfy (DTS) requirements such as putting a certain amount of insulation in the roof and walls. The use of COLORBOND® Coolmax® steel may or may not provide concessions as the requirements are necessarily conservative. • Use energy efficiency verification software, which gives you wider scope. This is the more common method for commercial buildings because the cost of the expert modelling is insignificant compared with the potential efficiency gains that can be made over using DTS measures. The use of COLORBOND® Coolmax® steel for roofing in the verification software is likely to provide the most benefit. For instance, a reduction of roof insulation may then lead to a roof spacer not being required. Alternatively the use of COLORBOND® Coolmax® steel may compensate for an underperforming element or an el
